SASH FASTENER.

Application filed September 4, 1924. Serial No. 735,727.

My invention relates to improvements 1n window sash fasteners, itsprincipal ob ect being the production of sash fasteners of thischaracter which shall be simple and 1nex ensive to manufacture and whichshall e ectively operate to prevent the open1ng ofthe sashes beyond apredetermined distance.

Other and further objects and advantages will appear from theaccompanying description, the invention consisting n the novel sash lockand parts thereof hereinafter more particularly described and thenspecified 1n the claims. i

In the accompanying drawing 1llustrat1ng a practical embodiment of theinvention:

Fig. 1 is a front elevation of a fragmentary portion of two slidablewindow sashes showing the invention applied thereto.

Fig. 2 is a vertical section on the hue 2-2 of Fig. 1. a

Fig. 3 is a horizontal section on the line 3 30f Fig. 1.

Fig. 4 is a sectional view taken through a portion of the device butshowing a modification.

Fig.5 is a plan view of anism of Fig. .4.

Fig. 6 is a key for operating the mechanism of Fig. 4.

Referring in detail to the several figures of the drawing andparticularly Figs. 1 to 3, inclusive:

1 indicates a side rail and 2 the lower rail of an upper window sash,the window pane thereof being indicated at 3. window pane of the lowerwindow sash is indicated at 4 while the upper rail and a side railthereof are indicated respectively a part of the mech at 5 and 6. Thesaid window sashes areboth slidable towards and away from each other insuitable channels or guideways m a window frame. 7

Secured to the side rail 1 of the upper sash by suitable screws 7 is aplate 8 provided with upper and lower laterally and inwardly extendingbrackets 9 receiving and supportlng a vertical rod 10, substantiallysquared as shown and provided with sharp corners. 11 indicates afastening member provided with a screw-threaded opening through which ascrew-threaded shaft 12 is threaded, the inner end of said shaft beingprovided with a head 13 which is recessed as at 13 which recess receivesthe end of a spring 14; hearing against the rod 10. A winged nut 15 orother actuator is also threaded over the outer end of the shaft 12. 16indicates arms preferably integral with the locking member 11, said armsbeing each provided with a round opening slidably receiving the rod 10.A. U-piece 17 is also provided having an opening slidably recelving theshaft 12 as shown in Fig. 3, the head 13 of said shaft acting to preventremoval of said U-piece' when the parts are assembled. The legs 18 ofsaid U-piece are each provided withround openings slidably receiving therod 10.

The device described permits the sashes or either of them to be openedand locked against further opening a distance limited by the length ofthe rod 10, the lower one being shown partially opened in Figs. 1 and 2with the lower portion or base of the fastening member 11 engaging theupper rail 5 of the lower sash. If the winged nut 15 has then beentightened the upper'sash may then not be lowered or the lower sashraised until the nut has been loosened and the device swung around onthe rod 10 into'the position shown in dotted lines in Fig. 3.

When the winged nut 15 is tightened a double clamping action in twodirections is effected. The tightening of the nut presses the member 11forwardly and jams the edges of therod 10 against the walls of the roundopenings in the arms 16. It also causes the head 13 to pull the U-shapedpiece 17 rearwardly whereby the edges of the rod 10 are jammed againstthe walls ofthe round openings in the legs 18. When the device is not inuse and the nut 15 is loose the spring 14 acts to prevent the devicefrom swinging or swivelling on the rod 10. It will be noted furthermorethat the plate 8 acts as a stop to prevent the fastening member 11 frombeing swung around in one direction further than operativeposition orthe osition shown in Fig. 1 as the arms 16 Wllltllfill engage the edgeof the plate and also prevents a movement. further than that of oper--ative position, and in the other direction as the ends of the arms 16will then engage the rear face of the inner side of the plate. In otherwords the plate itself prevents the fastening member from being swungthrough an arc of more than 90.

In the modification of Figs. 4 to 6 inclusive I dispense with the wingednut and proill) ' vide the fastening member with an opening 7 19receiving the shaft 12 which in this case 1 have provided a special formof key2t having fork members adapted to enter the is not threaded butwhich is provided with a-thre'aded stem 20 extending through thefastening member and projecting into "a larger round opening 21 in theend 'of the fastening member.

and with slots 23 therein. As is obvious, the member 22 acts as a nutand rotationof the same on the threaded stem will effect thefs a'meresults as in the preferred form of the invention. To rotate it,however, I

slots 23 of the nut 22 and being also provided with an intermediate slotor opening 25;

adapted to receive the stem 20 when thenut is rotated ina direction todraw the stem outwardly. v v

It will be understood to be within the scope of my invention in somecases to make the rod 10 round and to form the openings in the arms 16and legs 18 squared or other than round. It will also be understood thatin some c'ases'I may attach the plate 8 to.

the window frame and have the device'effect-ive' as respects one sashonly.
